Choosing the best heat pump for a freezing room is not easy. The Northeast Energy Efficiency Partnerships (NEEP) heat pump directory contains over 30,000 different models, each with a huge number of features. Hyper-Heating (h2i), manufactured by Mitsubishi, is the best heat pump for cold environments. Not only can these heat pumps generate usable heat down to -13 degrees Fahrenheit, they also maintain full heating output down to 5 degrees Fahrenheit. Heating seasonal performance factors (HSPF) for h2i models range from 10.5 to 12, while seasonal energy efficiency ratios (SEER) for cooling range from 15 to 20. Coefficients of performance (COP) of up to 2.88 are maintained by their heat pumps at temperatures as low as 5 degrees Fahrenheit.
Both ducted and ductless configurations of Mitsubishi’s Hyper-Heating system are available. We recommend the Fujitsu AOU series as the second-best heat pump for chilly environments. Models with a variable fan speed generate 75%–95% as much heat at 5F as they do at 47F. They have a cold tolerance of -10 degrees Fahrenheit.
Daikin’s Fit and Aurora lines have great cold climate specs. The Fit (RZQ) line can work at full heating capacity down to 5F. The relatively new Aurora (RXL) series can work down to -13F. HSPF ratings between 9 and 10.5, and SEER ratings between 16 and 18.5.
The most important factor is the installer:
A heat pump is a marvel of state-of-the-art, environmentally friendly engineering. Proper fit and installation are more critical than the brand of product used. Get recommendations, check prices, and interview your installer carefully. HVAC (heating, ventilation, and air conditioning) professionals familiar with heat pumps can assess the efficiency of your home.

Why proper heat pump sizing matters:
To put it simply, heat pumps aren’t like furnaces or electric baseboard heaters. The quantity of heat they give out varies with the ambient temperature. It doesn’t matter how frigid it is; there is still life force in the air. In order to absorb this heat, a heat pump uses the opposite process, expanding and compressing refrigerants.
Oversizing a heat pump increases the frequency with which it must start and stop, which in turn increases energy use, system wear, and temperature fluctuations. As previously mentioned, under-heating becomes more noticeable when using a heat pump that is too small. If you have a decent smart thermostat, you can find out how much energy your heating system consumes on the coldest day of the year.
Why we recommend the Mitsubishi H2i heat pump:
We inquired on Twitter and surveyed contractors about the best heat pumps for chilly climates, and Mitsubishi kept coming up as a top recommendation. This makes perfect sense. Its heat pumps are widely distributed and supported by installers, and they have better heat capacity at lower outside temperatures.
If you’re looking for raw numbers, the Mitsubishi Hyper-Heating (h2i) series is your best bet. In temperatures as low as 5 degrees Fahrenheit, an h2i heat pump can provide its full design heating capability. That might mean the whole winter season for some places. Insulate your house properly and choose an h2i heat pump that can handle your heating needs, and you’re probably ready to make the transition.For better performance, a reliable HVAC system should be installed with the heat pump. Hire experts for heating installation in Manhattan and see how they can help you.
But even if you have a very harsh winter, you still have options. Even when the temperature drops below -13 degrees Fahrenheit, an h2i pump may continue to operate, providing around 80% of its full heat capacity. For short periods, you can simply turn down the thermostat and bundle up, but for longer periods of freezing weather, you’ll need a backup heating system, whether you maintain your current system or add electric backups.
It’s not only in theoretically chilly places that people choose Mitsubishi heat pumps; the actual world is freezing too. This is based on data from the Massachusetts Clean Energy Center’s heat pump installation database, which goes all the way up to the year 2019. Installs of Mitsubishi heat pumps are almost 2.8 times higher than those of Fujitsu, the next most popular brand. When you download the information and look around, you’ll see a huge variety of dwelling sizes and heating requirements throughout a state with winter temperatures that often fall below 0° F.
